🖼 A hidden picture is waiting inside the grid. Use the numbers above each column and beside each row to work out which squares to fill in — click a square to fill it in, click again to clear it. Prefer paper? It also prints as a blank grid, with a fold-over answer key at the bottom — fold it backward along the dotted line before you start.
Each number tells you how many squares in a row to fill in that line, in order. A clue of 2 2 means: fill 2 squares, leave at least one blank, then fill 2 more.

Nonograms (also called picross, griddlers, or hanjie) are logic puzzles that hide a picture inside a grid of numbers:
This puzzle is a 15×15 grid. For the full method, edge logic, and tougher techniques once you're ready to level up, read our complete guide to nonograms and advanced nonogram techniques.
Here's how Mr. Puzzle approaches this one. Rows are numbered top to bottom and columns left to right.
Begin your "what if" tests at the top. Row 1's single square has very few places it can go once you check what rows 2 and 3 need underneath it.
There's exactly one answer, but you can't get there one line at a time. The thin, interlocking shapes mean you'll need the contradiction technique from our advanced guide. A good one to come back to.
Mr. Puzzle built Easy as ABC for back-to-school season — the letters A, B, and C stacked together in one grid, a nod to the very first thing most English-speaking kids learn to recite in school. Remember your ABCs? This puzzle is a picture of exactly that: the alphabet itself, reduced to its opening three letters and rebuilt one filled square at a time. Despite the name, it is rated Hard: with so few filled squares, the clues give line logic very little to grip, so you will need to test cells for contradictions to make progress.
